CENTRIFUGAL DRAINING-MACHINE.

Specification of Letters Patent No. 10,060, dated September 27, 1853 T0 alt whom it may concern: 7

Be it known that I, WVILLIAM RICHARD- SON, of the city of New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Im provements in Machines for Elevating \Vater, called a Centrifugal Draining-Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which Figure 1, is an elevation in perspective and Fig. 2 a vertical central section.

The difference between this and all other centrifugal machines, for directing water, consists in this: that in others, valves or priming or filling have been necessary; or the machine in its motion had to contend with the friction of the water in which it was revolved; whereas in this the water is excluded, by the machinery being placed in a water tight reservoir or box, and the water is received below the level of the surrounding water through tubes,thus priming itself, and it is elevated and discharged through tubes entirely without valves, thus avoiding liability of obstruction thereof and resistance of water exterior to the machinery and reaction upon the motor power employed; and as it is by the water remaining in the radial and annular tubes alone (not by the central one) that any centrifugal eifect is produced, it is always in a condition to operate effectually without advantageous aid in priming, or liability of being out of order as in other hydraulics, the water ascending through the inclined or oblique tubes, and flowing therein by natural laws without any material friction; the hol low rings serving as stadia for the elevation of water to different heights as well as giving compactness and strength of form to the machine.

To enable others skilled in the art to make and use my invention I will describe its construction and operation.

In the accompanying drawings 1, represents a vertical shaft; to the upper end thereof the motive power may be applied by suitable gearing; at its lower end or base it is enlarged forming an open tube called the supply bulb B. This rests and revolves upon a cylindrical tube A (or on a pivot fixed therein) making a water tight revolving joint; the tube A is secured water tight in the bottomsof the tub Y, Y, and forms an induction tube for the water into the machine.

WV, are horizontal radial hollow arms, inserted into and opening in the bulb B; at their outer ends uniting with and opening into a hollow circular horizontal tube or ring D D; at a desired height to which the water is to be elevated, is placed a second circular tube G G of a larger diameter than the lower one; it is also connected with the central shaft I, by arms X X; between D and G and furnishing a communication therewith are ascending tubes E, E, placed slightly inclined; and as a means of communication by which the supply is kept up. Other ascending tubes F, F, connected and opening into the bulb B and upper ring G are placed with a considerable inclination. The short tubes H, H, are for the discharge of the water into a circular trough exterior to G G from which it may be conveyed off at the higher level.

Y Y is a tube or water tight case, which is sunk below the level of the surrounding water, excluding it from the machine except when it enters the bulb B through the open cylinder tube A and bottom of Y.

By gearing to the shaft 1, in any convenient manner suitable machinery for revolving it, the machine may be set in rapid motion, in the direction of the arrow O, P, and the water-line being above the level of the supply tubes and lower circular tube D, it rises through the induction tube A and fills said circular tube by means of tubes 7, W, and bulb B and also the ends of the several rising tubes E E and F, F. The machine being started and rapidly turned when revolving the water is pressed by centrifugal force proportionate to velocity, against the outer walls of the circular tube D D; and in the supply tubes W, it is pressed in like manner toward their outer extremities; consequently it rises in the tubes E, E, and F, F, to the upper circular tube G G where it is, in like manner as below pressed by its centrifugal force into and through the discharge jets H, H, into a circular trough placed under said jets.

Having described the nature of my improved centrifugal drawing machine what I claim as my invention and desire to secure by Letters Patent is The arrangement in the tub Y of the induction tube A, supply bulb B, and annular tube or ring D D placed below the water line exterior of the tub, in combination with the ascending tubes E E and F, F, and a second annular tube G having discharges H H, for the purpose of self priming, pro- 10 tecting the machine from the resistance of water exterior thereto, and giving steadiness to the ascending column of Water discharged by the machine.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.
